Smoldering oxygen consumption and product synchronous test analysis device and method for mining high polymer material

The invention, which belongs to the technical field of coal mine safety, relates to a smoldering oxygen consumption and product synchronous test analysis device and method for a mining high polymer material. The method includes the steps that: a mining reaction type high polymer material solidified body is placed in a smoldering reaction chamber, and the high polymer material solidified body is heated by a heating device; during heating, a test gas storage tank is opened, a gas flow in contact with the solidified body is controlled through a gas flow control device to simulate the undergroundgas flow speeds in different underground application environments truly; testing temperature changes of different positions in the solidified body under different time conditions in the smoldering process through a thermocouple; testing the gas flow and the oxygen concentration of a gas outlet side of the smoldering reaction chamber to obtain an oxygen consumption rate of the polymer material solidified body in the smolde
